PAPER-FOLDING MACHINE.

Application led May 16, 1924. Serial No. 713,719.

To all whom t 'may concern:

Be it known that I, WALTER G. TRAUTMAN, a citizen of the United States of America, residing at Cleveland Heights, in the county of Cuyahoga and State of (lhio, have invented certain new and useful Improvements in Paper-Folding Machines, of which the following is a specification.

My invention relates to improvements in paperfolding machines and has for its object the equipment and mounting of the folding plates of such machines whereby they may be more readily adjusted to suit the varying requirements of the folding machine and may be handled without removal from the support or frame. I preferably associate therewith a fixed transverse feed.

Hitherto it has been necessary bodily to remove or insertthe plates associated with the folding rolls of a paper-folding machine; substitutiiig such folding plates, when required by detiectors positioned before the requisite set or sets-of folding rolls. This necessarily entails considerable labor and time for adjusting the paper-folding machine to accomplish the different folding operations required by different jobs.

Accordingly, l have improved this class of paper-folding machine by mounting thev folding plates s idably within the frame for easy adjustment toward and from the coacting rolls. Moreover, the folding plates preferably are equipped with individual deflector lmembers adapted to be actuated into and out of operative relation with respect t said folding plates and rolls. Thus my improvements render it unnecessary to remove either tlie folding plates or the deflectors from themachine, since they are capable of every adjustment required thereof merely by sliding the folding/plates into or out of operativerelation with the corre'- spondiiig rolls and adjusting/the associated deflectors'respectively in their inoperative or operative positions, as required.

lThe features of my improvement may be made clear and the utility may be fully explained by making reference to the accompanying drawings. wherein:

Figure l is a plan view, partially broken away, illustrating a papenr'olding machine equipped with my improvements,

Fig. 2 is a longitudinal sectional view thereof,

Fig. 3 is an enlarged fragmentary section on line 3 3, Fig. 2,

Fig. 4 is an enlarged transverse section centrally broken away online 4 4, Fig. 2,

Fig. 5 is another enlarged fragmentary section illustrating the adjustable def-lector,

Fig. 6 is an enlarged fragmentary section and plan on line 6-6. Fig. 7, showing the folding rolls and deflectors in association willi the folding rolls,

Fig. 7 is a fragmentary vertical section on line 7 7, Fig. 6, and Fig. 8 shows a modification in longitudinal section.

Throughout the several figures of the drawinn's I have employed the saine character of reference to indicate similar parts.

Attention may initially be directed to the somewhat 'diagrammatic showing lof Fig. 2 wherein the frame a supports thefeed table adapted to convey the sheets between the feeding rolls L. o to the series of folding and buckling rolls c, d, c, f, g and It. The folding plates z', j. L and Z aie operatively associated with said series of rolls and are slidably mounted within the frame, two by two, on either side yof said series of rolls.

g Each vof said folding plates is provided with a pivoted delector member fi', j', c and Z vof suitable shape adapted individually to be adjusted in advance of the throats of their respective openings for the signatures, whereby the particular folding plate may be rendered `temporarily inoperative, merely by withdrawing said folding plates and securing them in their rearward positions of adjustment within their slides. As shown in the drawings, only the second folding plate jef the sei'ies is left operative to permit the formation of va fold therein, while the detlector members serve otherwise to direct the signature through the rolls as a continuous pass without operating thereon.V As indicated, inoreparticularly in Fig. 7. the folding and buckling rolls are ivotedly mounted at their ends upon brac et members and are spring pressed-to secure their resilient engagement in accordance with the wellknown manner. Moreover, the deectors are Seen to be of slightly varying shapes in order to conform to the direction initially assumed by the signature in passing between the respective pairs ofrolls.

From the foregoing it will be understood that any folds may be provided 4for or omit yted from the-operation of the folding apparatus, so that it is desirable to provide a fixed transverse feed or conveyor table, as best shown diagran'imatically in Fig. 8. Thus, int-hemodification shown, and with the adjustment rendering inoperative all but the second folding plate.y the signatures will pass successively through the rolls with but a single folding operation and thence between the feeding rolls m fm and 11, n to the roller-bed o of the transverse conveyor. These rolls 0, .it may be assumed` will feed the signatures toward the opposite side of the folding machine and the importance of having this transverse feed in a fixed or predetermined position is emphasized in the modern folding machine which commonly requires additional auxiliary mechanism to accomplish additional transverse folds or other operations as more fully explained in m co-pendng application Ser. No. 713.718. T ese features, however. form no part of present inventionl which relates .more particularly to the adjustment of the folding plates and their deflector members in association with the fixed transverse feed per se.

Having now described the preferred e1nbodiment of my invention and the operation thereof, I claim as new and desire to secure by Letters Patent, together with such modifications as may be made by. those ordinarily skilled'in the art, the following:

1."In a aper-folding machine, the combination wlth its frame provided with Vlateral supports of a plurality of folding plates slidably mounted respectively upon said supports, and deflector members adjustably positioned forwardly of said folding plates and adapted to be actuated into and out of operative position, substantially as set forth.

2. In a paper-folding machine, the combination lwith its frame, provided with lateral supports of a plurality of folding plates slidably mounted respectively upon said supports, and deflector members pivotedv each to each upon the forward portions of said folding plates -whereby they are adapted to be actuated independently into positions in advance ofthe respective folding plates or into inoperative positions for said detlectors,

y substantially as set forth.

Y 3. In a paper-folding machine, the combi-y nation with its frame .provided willi lateral supports of a. plurality of folding plates` slidably mounted respectively upon said supports, folding and buckling rolls associated with said folding plates and means forindividually securing the folding plates in forward and rearward positions of adjustment with respect to the folding and buckling rolls, substantially as set forth.

4. rl`he combination,with a set of folding and buckling rolls in a paper-folding machine` ot' a fo-lding plate associated therewith. means for adjusting it toward and from said rolls and a detlector member adjustably positioned upon the forward portion ol' .said folding plate adapted to be actuated between said folding plate and rolls when the former is rearwardly positioned, substantially as set forth.

n The combination with a set of folding and buckling rolls in a `paper-folding machine. of a folding plate operatively associated therewith, a slide supporting said folding plate before and adjacent to the rolls and permitting its adjustment with respect thereto. and adjustable means provided upon said folding platev for temporarily blocking the, entrance of the signature to the throat thereof, substantially as set forth.

(l. ln a paper-folding machine, the combination with a plurality of folding plates. of their associatedy foldiiu r and buckling rolls. adjustable means provided upon each of said folding plates for 'emporarily blocking the entrance of the signatures thereto, and a fixed transverse conveyor stationarily mounted within the folding machine below the lower-most set of rolls. whereby signatures of any desired number of folds` maybe fed laterally of the'niachine in rnedeter mined position. substantially as set forth.

7. ln a Wiper-folding machine, the combination with its frame provided willi lateral .supports of a plurality of folding plates slidably mounted respectively upon `said .supports` foldingand buckling rolls operatiwly associated with said folding plates. dctlector means provided upon each of said folding plates adapted respectively to be interposed between them and the rolls. and a transverse feeding conveyor tixedly positioned within the frame beyond the lowermost rolls and adapted to receive the folded signatures therefrom. substantially as set forth.

ln testimony whereof l do now atlix my signature.
